Unable to get GIT GUI to start on Windows XP - Git-1.9.4-preview20140929

Dear Support

Can you please assist me, as I've got this issue starting up GIT GUI on Windows XP, Service Pack 3

Whenever I try to start-up GIT GUI, I get the following error message "Error in startup script", please see below.

I've been searching the web forums for weeks now and speaking to other members of my team, but know one has been able to find the solution.

Any assistance you can give me would be very much appreciated.

Kind regards
